All of the names I've come up with for our peas seem to come from their personalities, so it's hard to suggest names for a bird I haven't met.
But you've named your other girls after fictional heroines, I wonder if you might stay with that theme?
Cinderella? (seems kind of long, though)
Alice? (of Wonderland fame)
hmm....nothing's coming to me....

She is best friends with Xena and one day when one of my older white peachicks walked into the large pen (I left their door open to see if one would come out) and my no name peachick walked up to the white peachick, which was about twice her size, looked at the larger bird, then flapped her wings and kicked at the larger chick a twice and the peachick ran away scared after being attacked by a little chick! It was one of the most amazing things I have seen for a little peachick to take on a peachick twice her size. So I would say she is bold and maybe tough. Trixie is a cute name though...
